New Clutch slipping under load...WAS: [DeTomaso] NPC - Clutch Disengagment

[Mad Dog Antenucci]

Will, Motown, Curt, All,
   
    I have another problem now...I had the same problem as Motown had and it turned out to be the "master cyl" after replacing the engine,flywheel and clutch....After installing a  new master and clutch slave and readjusting linkgage last week the gears and linkgage is right on....BUT when I took the car out on the road
   
   I noticed that the clutch now wants to slip 'under load' like its partially engaged ....again the flywheel and clutch are new so I think its an adjustment issue but just don';t know where to adjust. The clutch engagement is set pretty short to the floor...perhaps too short?

  I'm just guessing here, but the release fork needs to move about 2" when
measured where the slave attaches to the release fork. I'm not sure where
the 1/10" is measured, but I doubt that's enough.

He says the pedal is heavy and the motion is similar to when it was
working, so I would believe that it isn't air in the system. While it
is difficult to measure the amount of movement at the clutch disc, he
believes it is approximately 1/10". I would suspect that this is enough.

Thanks
